[Market-farming] organic standards for cleaning out conventionalboom sprayer

When Marlin was using chemicals on the dairy farm, he would put 100% ammonia in the sprayer and spray it out.  Couldn't it be sprayed on a road?
We have hard limestone water.  That will also leave a white line or film where it sets.  An acid like vinegar or a Lime-A-Way product can remove that kind of deposit.  Hard water can also clog sprayer nozzles.
Best Wishes,

  Subject: [Market-farming] organic standards for cleaning out conventionalboom sprayer


  We recently purchased a formerly conventional boom sprayer for use with possibly some biodynamic sprays and definitely compost tea and some other liquid nutrients.  I would like to do a 1-time conversion to organic with the sprayer, but have no idea what the organic standards require (we're not actually certified - but I believe in the standards).  I'm also concerned about a quantity of dry whitish material on the bottom of the tank - how would I safely get rid of what ever it is?  The sprayer was used for round-up for weed control on berries and small fruits - I don't know if any other materials were used in it.  I have no experience with conventional stuff - should I be wearing rubber gloves, respirator, etc?
  Thanks much for any input!
